Let's start out that at the very beginning husband asked for both my number and my sister's number... we've been married 5 years now. He always showed interest in her whenever arpund.. pulled out chair for her which he never does me.. when she said he needed to start taking more pictures of his family he did. We recently went on a trip together and sister was braless the whole time.. I caught him looking a lot.. also when we got back home after trip he must have still been thinking about it because he had looked up on his phone "sister in law braless". Agywr this we had a family function and they were both there together I caught him looking at her butt like really checking it out. And as she was getting her picture taken he had the biggest smile on his face. I'm so annoyed because I'm married to this man and have children with him.. but now at family functions it's so hard having them in the same room together.. help!
